Abstract
An image forming apparatus that is capable of executing image forming operation includes an image bearing member, a developer carrying member that faces the image bearing member in a state of keeping a predetermined gap therefrom and develops a latent image on the image bearing member using developer, a frame that supports the developer carrying member, and applying unit that apply developing voltage, in which DC voltage and AC voltage are superimposed, to the developer carrying member. A conductive member is disposed in the frame, a detecting unit detects AC current induced in the conductive member by applying the developing voltage to the developer carrying member, and a control portion controls the applying unit. The control portion controls the developing voltage in the image forming operation, based on the AC current which the detecting unit detects in a case where the voltage is applied by the applying unit.
